chines, particularly to pedally operatedtypes and has as its object to 'provide an easily Operated grind-stone turning appara-l tus capable of being actuated by one person having both hands free.

A further purpose is to produce a water containing pan so arranged as to be movable limitedly with respect to the grinding wheel partially immersed therein.

These and other Objects, which will be come more apparent as the description progresses, are attained by the novel construction and combination of parts hereafter described and shown in the accompanying drawing, formingra material part of this disclosure, and in whcht Figure l is a partial plan view showing an embodiment of the device.

Figure 2 is a perspective view of the same, parts being broken away to show the construction.

The device consists of four posts10 connected in pairs by side beams 11 and 12, respectively at the top and near the bottoms, and cross beams 13 and'l at the tops, forming a substantial frame, which also includes a Vwide beam 1,5 at the left hand Side.

Attached below the beams 12'are brackets 1G in which is revolubly-mounted a shaft 17 having a central p edal 20 and an extending end crank 19.

link 2l is connected with the extending crank 19, its opposite end engaging' a crankpin fixed in the side ot a gear wheel 29 meshing with a pinion 28 fixed to the side of the spindle 27 fixed in the beam l5 directly over the Shaft 17.

The spur gear 29, meshing with the pinion. is mounted on a spindle 30 and also meshes with a smaller gear 31 lixed on the extending end of a shaft 32.

Std shaft is carried in bearings 33 fixed on t e .ters

beams 11 and held from longitudinal movement by thehub of the gear 3l and a. collar 34 at itsopp'osite outer end.

Fixed on the middle of the'shaft 32 is a l grindstone 35 or the like, which upon operating the treadle 20 will obviously be rotated, but at a lower speed than the iiywheel 26, and hence, dueto the reduction of the gearing, quite powerfully.

pan 36, semi-circular in proiile and having its sides spaced to clear the stone 35, has its sides notched to clear the shaft and extends to about the center of the stone, the

pan being adapted to contain water in which the wheel rotates.

his pan is supported at its front andV rear by flat plates 37 containing elongated slots 38 engaging pins 39 fixed in the beams 13 and 14', the pin in the beam 13 having a thumb nut 40 adapted to clamp the pin in adjustment, the slots permitting the pan to be moved to and from the stone in an obvi ous manner.

A cover plate 41 is also provided with holes vto engage the pins 39, thus forming a level table on which work can be disposed, the stone extending through a central opening` in the plate.

A seat 18 for the operator is adjustably secured to one of the posts by a band 21 and support 22, providing a convenient rest during` operation. y

vconvenient and easily Operated grinding appara-tus has been disclosed which fully meets the objects set forth.

Having thus described my invention, what I' claim as new and desire to secure by Let- Patent, is r- A grinder comprising a rectangular trame, a grindstone rotatable therein, an actuating gear train for said grindstoue, pedal means t'or actuating said train, a pan in which said grindstone operates, said pan having slotted supports resting on thekt'ront and rear elements of saidV frame substantially level with the axis ot' the stone, to act as a support for work to be ground, and being adjustable to or from theV stone, and means for clamping Said pan in adjustment.

In witness whereof I alix my signature.
